In an interview with GeekWire, Chambers shared that he'd been obsessed with Harry Potter since before his two daughters were born, and now the obsession is a part of the family. And after coming up with the blockbuster idea about half a year ago, he decided to quit his job and devote weeks of work (and thousands of dollars) into the project, which takes up his driveway in his Ballard neighborhood.

Chambers, who has a background in illustration and construction, clearly put his heart into every detail of the project, which encompasses about six storefronts that feature digital painting "windows" inside and 3-D printed props of his own making. And on Halloween, the installation really came alive with actors playing out some of the Potterverse's most recognizable characters.

While much of the project was done in the name of pure fun, there's another side to Chambers's project: Some of the proceeds from the ticketed attraction are going to support research into pancreatic cancer, which took the life of his family friend Matt Bencke.

While it's unclear how long this Diagon Alley will remain up, Chambers is already looking forward to his next project: "I’ve thought it would be cool to do a Millennium Falcon. On the roof."
